It was first reported back in 2024 that Samsung could make AI chips for OpenAI, the company behind ChatGPT. OpenAI CEO Sam Altman has made multiple trips to South Korea since then, meeting with top Samsung leaders and inking some deals. However, as far as custom chips go, those plans may have hit a roadblock, according to a new report out of South Korea.No confirmation that the deal has fallen throughSamsung has reportedly been working on an inference neural processing unit for OpenAI, based on the ARM architecture. It's said that considerable progress has been made in the preliminary develoment stage. It's now said that work has cooled off due to the strategic differences between OpenAI and Samsung Electronics.This might explain Samsung's recent investment in another leading US AI startup Anthropic, the company behind Claude. A recent report has also claimed that Samsung might make AI chips for Anthropic.Even if Samsung and OpenAI aren't seeing eye to eye on chips right now, the two companies are collaborating in various other fields. Among the wide-ranging agreements signed between them late last year, many Samsung companies signed on to provide different services to OpenAI. For example, Samsung SDS will jointly develop AI data centers with OpenAI. Samsung is also likely to provide memory semiconductors to the AI startup.
